Hi Biddy,
you have the classic symptoms of burnt solenoid contacts. What happens when you turn the key is that the solenoid pulls in, which makes a click. It's supposed to hit two brass contacts at the end of its stroke, and connect the two together. This then allows current to flow to the motor itself, which then turns the engine over. If these contacts are burnt, they don't connect properly so you have to keep trying until they do. Sometimes they will connect second try, sometimes it takes many tries before they eventually connect and turn the starter motor.
As you rightly say, it makes no difference whether the engine is hot or cold. It's purely a matter of luck whether the contacts connect first time that you turn the key, or 21st time.
What Mike says sounds like a good idea.
